Can a singe Dropbox’ed 1Password db be shared between 1Password v4 & v3

I had this exact problem over and over, with some help from Agile I found the answer here: http://help.agile.ws/1Password3/configure_dropbox_on_mac.html

Here is the important part:

To configure 1Password on your other Macs, first setup Dropbox, then make sure you have the latest version of 1Password installed and running.

Locate your 1Password.agilekeychain file in your Dropbox folder. If it has a green check mark badge indicating that the sync is complete, double click it,

and 1Password will confirm that you want to use this new location. Important If it shows the blue syncing badge rather than the green check mark badge, wait until the badge is a green check mark before opening the file. Failure to do so could result in data corruption.

Applescript has a parameter administrator privileges which adding it to your script will execute the command as Administrator.

Extracted from Apple's Apple Script Language Guide:

Execute the command as the administrator? Once a script is correctly authenticated, it will not ask for authentication again for five minutes. The elevated privileges and the grace period do not extend to any other scripts or to the rest of the system. For security reasons, you may not tell another application to do shell script with administrator privileges. Put the command outside of any tell block, or put it inside a tell me block. Default Value: false

So it should be something like do shell script "whatEver" with administrator privileges.
